The plier stapler was first produced in 1948. Its practical, reliable design hasn't altered, although its functionality has been improved through technical innovations. It is built to last - each stapler is tested piece by piece, and it has a patented anti jamming device; in fact it comes with a life time guarantee. It is light and effortless to use. The stapler is made entirely of metal and is coated with a lead free enamel paint, to prevent wear and corrosion. The stapler comes with a box of 4/6 staples. Extra staples available here.
